This Sauron meme is obviously directed at current Republican frontrunner (shudder) Donald Trump, and his campaign slogan, "Make America Great Again," whatever that means.
As is often the case with these memes, there's often a point to it. The prospect of such a dangerous man becoming American president is very concerning. Equally concerning is his high level of support from American evangelical Christians.
This editorial from The Christian Post is a wakeup call to these Christians before they vote in upcoming primaries, particularly the crucial Super Tuesday contests.
